Unfortunantly, RFIDs for cattle cost WAY more than the physical chips themselves. There are various organizations which are government approved for their chips/scanners/systems, etc.
And then there are the associations... National Cattlemens Beef Association (The Beef Checkoff), Angus, Charlais, Hereford, Red Poll, etc. who all are in on the action as well.
These organizations make "exclusive deals" with the chip/scanner/systems producers where if you raise Beef, you will use that particular companies system or your cattle won't be registered.
And oh yeah, the Associations are all Government Approved Registries... So there's no competition there at all.
There's a whole industry ramped up to skim every nickle possible from the Beef Producer on this one. It's all a big shake down.
